10 Essential Facts About Thrust Ball Bearings You Need to Know
1. What Are Thrust Ball Bearings?
Thrust ball bearings are specialized bearings designed specifically to handle axial loads, which are forces acting parallel to the axis of rotation. Unlike radial ball bearings, which accommodate loads perpendicular to the axis, thrust ball bearings are perfect for applications where there is a need to support heavy axial loads. As stated by Dr. George D. Lichtenberg, a renowned mechanical engineer, "Thrust ball bearings are essential in various industrial and automotive applications due to their unique ability to support these loads effectively."
